Evaporation‐induced intercalation of nanosheets of organosilica, organoclay or various organic polymers within the interlayer spaces of an oriented bacteriorhodopsin/lipid membrane mesolamellar film is used to prepare stable, self‐supporting biofunctional hybrid nanocomposites with photochromic and photoelectric properties. Compared with unmodified purple membrane films, mesolamellar nanocomposites containing intercalated organosilica exhibit enhanced stability in their photoelectric response at high relative humidity.
